This article is a little rambling and is only loosely related to anti-piracy
(1) There are all sorts of subsidies internationally for movie related industries/services. (2) US studios are "exporting jobs" by taking advantage of these subsidies to to various editing tasks overseas. (3) This is unfair because of various WTO rules and principles of free trade. (4) US states are responding by doing the same (5) Anti piracy is a higher priority for the US industry.
I don't really see the last point as related to the first 4. The other points are part of a bigger picture in the ongoing globalization process. Countries are "competing" with each other in all sorts of ways. They compete for jobs, FDI & tax revenue in ways they didn't previously, at least not as much. This gets translated into tax breaks, subsidize and lots of other things.
IMO the most interesting part of all this is that a movie cannot be said to be a US, French or South African production anymore. Shooting takes place all over the place. Editing and post production now happen place all over the place too. "Quality" in the form of the best actors or best special effects people is important. Money always flowed more freely than goods, services or labour so that comes from everywhere too as it always has.
IMO the industry is in a unique position. Much of the work is easy to parcel. The 'firm' comes into existence to make a film and then goes away so personal relationships, buildings, equipment and other things that keep firms monolithic (reduced transaction costs is usually considered the biggest advantage large firms have over individual actors transacting in spot markets, Ronald Coase's theoroms) are not much of a factor.
